Actually in myetherwallet scam, I am one of the stupid bitcoiner that being scam. They sent an email as the same as the email of campaign manager at bounty asking for my info like KYC and asking my private keys.I thought it was legit because campaign manager was always sent an email update to me. So next day I found out that my coin  was stole. So I can say that scam is the biggest crime here in cryptocurrency.
